BASE FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 271,653, dated February 6,1883.

Application filed December 1,1882. (N model.)

Improvement in Bases for Gas-Burners and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates to a base for gas-burners, made with a lateral arm adapted for the connection thereto of a drop-light tube.

Heretofore such a device has been con-' structed with a bifurcated channel for the flow of gas to the burner and drop-light, controlled by a single valve, so that the flow of gas may be directed to the burner and drop-light at the same time, or to either alone. This device is comparatively complicated and expensive, and

necessitates the use of a separate cock or valve below the base to shut off the gas from both burner and drop-light. g

The object of my invention is to simplify the construction of the base and provide for an independent control of each of the passages therein; and itconsistsof asimple base formed to fit upon the end of a gas-tube in the customary manner, and to receive a gas tip or o'burner of any approved description, provided with a lateral arm or offset cast in one piece with said base,and threaded to receive the fitting of a flexible tube, and with separate passages for the flow of gas from the lower end of the base, both to the burner and to the drop-light, each fitted with an independent stop or valve, whereby either may be opened or closed without reference to the other, and the use of a third distinct valve or cock to con- 0 trol the flow of gas to the base thereby dispensed with. I

In the accompanying drawings, Figure l is an elevation of my improved base fitted with 7 burner and glass shade, the latter being in 5 section; Fig. 2, a bottom view of the base,

and Fig. 3 a longitudinal section in line 00 m of Fig. 2.

My improved base for gas-burners is cast of metal, in substantially the form illustrated in 0 Figs. 1 and 3, with a main stem, A, and a lateral arm, B. The main stem terminates in a socket, 0, Fig. 3, which is threaded internally burner, E. A direct passage, F, is formed between the socket and burner, and governed by asmall valve or screw-plug operated by a thumb-screw, G, Fig. 2. The lateral arm B projects from the main stem A at an angle more or less acute therewith, so as to extend outward therefrom, with a downward inclination when the stem is fitted vertically upon the gas-tube, as shown in Fig. 1. The end of Y the arm is threaded exteriorly to receive a suitable nipple for connecting thereto a flexible tube for use with a drop light. An independent passage, H, Fig. 3, is pierced from the socket through to the outer end of the arm B, and is governed by a valve or screw-plug operated by a thumb-nut, G.

With this improved base the necessity of a benttube to pass over the edge of theglass globe, in order to use a drop-light in connection therewith, is avoided, and the simultaneous use of both a main burner and droplight is simply provided for, while the flexible drop-light tubing is entirely removed from the possibility of contact with the burner, and its attachment and detachment may at all times be readily accomplished with ease and facility.

My improved base and drop-light attachment can, moreover, be fitted to any gas-pipe as readily as an ordinaryburner.

I claim as my invention-- The combination, in a duplex base for gasburners, with its main stem A adapted to fit upon a gas-tube, and its lateral arm B adapted to receive a flexible drop-light tube, of separate independent passages F H, leading from the lower end of the base through the stem to the burner, and through the arm to the droplight tube, and of independent valves G G,

separately controlling said passages, all substantially in the manner and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
